Selection of optimal design, experimental study and mathematical modeling of magnetic field of low-speed synchronous generator with permanent

Abstract

Increased scientific and practical interest in the development, design, research and implementation of low-speed permanent
magnet synchronous generators is caused by the need to equip and fill various sectors of the national economy with efficient renewable energy sources based on the principles of wind, hydro and pneumatic energy. The impetus to the creative thinking of domestic and foreign science on the creation and introduction into production and life of new types of designs of magnetoelectric machines with excitation from permanent magnets is the emergence on the consumer market of a wide range of highly coercive permanent magnets based on rare-earth elements from neodymium-iron-boron alloy (NdFeB). In this paper, the design of a low-speed permanent magnet synchronous generator is proposed taking into account the full list of requirements for renewable energy sources accumulated by practical experience in creating such electromechanical converters. Along with the geometry description, the article presents the results of mathematical modeling of the magnetic field of a low-speed synchronous generator using the ANSYS (Maxswell) package confirmed by experimental studies of a prototype.
